PLOW.

Specification of Letters Patent.

Patented Aug. 6, 1907.

To all whom "it may concern:

Be it known that I, FURMAN HUFF, a citizen of the thereof and also toacquire a knowledge of the details ofconstruction and the means foreffecting the result, reference is to he had to thefollowing descriptionand accompanying drawings.

While the invention may be adapted to different forms and conditions bychanges in the structure and minor details without departing from thespirit or es-' sential features thereof, still the preferred embodimentis shown in the accompanying drawings, in which:

Figure 1 is a perspective view of a plow embodying the invention,showing the same inverted. Fig. 2 is a perspective view of the plowpoint and share. Fig. 3 is a perspective view of a portion of themold-board and land-side showing the throat piece and coupling bar inplace. Fig. f is a horizontal section. Fig. 5 is a section on the line:tx of Fig. 1. Fig. 6 is a detail perspective view of the throat piece.Fig. 7 is a perspective view of the plow point, share and front portionof the land-side. Fig. 8 is a perspective view of the box having the setscrew attached. Fig. 9 is a perspective view of the coupling bar.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

The plow point 1, share 2 and front portion 3 of the land-side are ofintegral formation. The land-side 4 is adapted to abut against the rearend of the part 3 and is held in place by the throat piece. Themoldboard 5 is of accustomed shape and construction and its lower edgeabuts against the upper edge of the share 2. The throat piece comprisestwo wings 6 and 7 and is secured to the mold-board and land-side andprojects a short distance beyond said parts as indicated most clearly inFig. 3 to underlap the share 2 and.

overlap the front portion 3 of the land-side. A lug 8 projects from theupper side of the wing 6 and is adapted to enter an opening 9 near thelower end of the plow share 2. The lug 10 projects outward from the wing7 and is adapted to enter an opening 10 near the rear end of the frontpart 3 of the land-side. These lugs 8 and 10 may be provided in theparts 6 and 7 of the throat piece in any manner preferably in a way toadmit of their ready replacement in the event of rupture or otherwisebeing displaced or unfitted for effective service. A bar 12 is securedto the outer portion of the plow share by means of a fastening 13 andsaid bar projects rearward from the plow share and has a longitudinalslot 14 and a threaded opening 15, the latter being at the rear end ofthe bar and in line with the slot 14. A box 16 is secured to the outerlower portion of the mold-board upon the under side thereof and isadapted to receive the end portion of the bar 12 extended in the rear ofthe plow share 2. The pin constituting the fastening 17 connecting thebox 16 to the mold-board passes through the slot 14 of the bar 12. Thebox 16 is closed at its rear end and at the bottom and sides, therebyprotecting and housing the rear portion of the bar 12. A set screw 18 ispassed through an opening in the rear end of the box 16 and itsprojecting end orhead is made angular to receive a wrench or suitabletool. A key 19 passed through an opening of the set screw engages theinner side of the closed end of the box 16 and prevents outwarddisplacement of said set screw, the shoulder at the inner end of thehead engaging with the outer side of the closed end of the box andlimiting the inward or forward movement of the set screw. The set screw18 is adapted to enter the opening 15 and to make screw threadconnection therewith with the result that the plow share is drawn closeagainst the mold-board and retained in place.

The fastening 13 may be a lug similar to lugs 8 and 10 so as to makedetachable connection with the plow share and thereby admit of thelatter being removed without necessitating the removal of bolts, theplow share being rendered detachable upon loosening the set screw 19,whereby the several lugs or fastenings 8, 10 and 13 may relax their holdupon the plow share and admit of its ready displacement.

Having thus described the invention, what is claimcd as new is:

1. The combination of a mold-board, a landside, a throat piece carriedby the mold-board and landside, a share re ceived by the throat pieceand abutting against the mold board, a box applied to one of themembers, a bar applied to the opposite member and received within thebox and having a pin and slot connection therewith, and a screw carriedby the box and engaging the bar to draw the two members together.

2. The combination of a mold-board, a landside, a throat piece carriedby the mold-board and landside, a share received by the throat piece andabutting against the mold board, a box, a pin connecting the box to oneof the members, a bar applied to the opposite member and received withinthe box, the said bar being formed with a slot through which the pinextends, and means cooperating with the bar for drawing the two memberstogether.

3. The combination of a mold-board, a landside, a throat piece carriedby the mold-board and landside, a share received by the throat piece andabutting against the moldboard, a box, a pin connecting the box to oneof the n1en1 bers, a bar applied to the opposite member and receivedwithin the box, the said bar being formed with a slot through which thebefore mentioned pin extends, and a screw carried by the box andengaging the bar to draw the two members together.

4. The combination of a mold-board, a landside, a throat piece carriedby the mold-board and landside, a share received by the throat piece andabutting against the moldboard, cooperating lugs and openings betweenthe share and the throat piece, a box applied to one of the members, abar carried by the opposite member and received within the box andhaving a pin and slot connection therewith, and a screw carried by thebox and engaging the bar to draw the two members together,

In testimony whereof I affix my signature in presence of two witnesses.
